What does blood in my semen mean?
Q: I've noticed blood streaks in my semen twice over the past 10 days. Is this a sign of something serious?
A: Seeing blood in your semen—a condition known as hematospermia—can be concerning, but it’s usually not a sign of anything serious, especially if it happens infrequently and without pain or other symptoms.
While the first thought many men have is cancer, bloody semen is rarely caused by prostate or testicular cancer. In fact, hematospermia is often temporary and benign, particularly in younger men or after recent medical procedures.
Q: What causes blood in semen?
A: There are several potential causes of hematospermia, including:
Recent medical procedures: This is the most common cause. For example, more than one-third of men experience hematospermia after a prostate biopsy, and cystoscopy can also lead to blood in semen, especially when biopsies are taken from the bladder lining.
Prostate enlargement (BPH): Benign prostatic hyperplasia can cause blood vessels to break, resulting in visible blood in the ejaculate.
Physical activity or trauma: Activities like bicycling or horseback riding, or direct injury to the groin or prostate, can sometimes result in hematospermia. Even frequent masturbation may be a factor.
Infections or inflammation: Infections of the prostate (prostatitis), urinary tract, or seminal vesicles can lead to hematospermia, especially when accompanied by symptoms like pain or fever.
Q: Should I be worried about cancer if I have blood in my semen?
A: Not necessarily. Cancer is a rare cause of hematospermia. Most cases resolve on their own and are not associated with any underlying disease, especially in men under 40. However, the concern may be greater in men over 40, particularly if blood in semen persists or is accompanied by other symptoms such as pain, urinary issues, or a history of cancer.
Q: When should I see a doctor about blood in semen?
A: Most of the time, hematospermia goes away without treatment. However, you should see your doctor if:
The blood in your semen lasts more than three weeks
It occurs multiple times in a short period
You also experience:
Pain during urination or ejaculation
Fever or chills
Blood in your urine
Testicular or pelvic pain
These symptoms may point to an infection or more serious underlying condition that requires evaluation and treatment.
Q: What’s the bottom line?
A: Hematospermia is rarely serious, and in most cases, no cause is ever found. But if it persists, recurs, or is accompanied by pain, fever, or urinary symptoms, it’s time to get checked out. A simple consultation with your doctor—or a specialist—can help rule out more serious conditions and offer peace of mind.
